Maryland fishermen are heading to the Potomac River after dark with an unusual goal: to shoot invasive "mutant fish" with compound bows before the predators spread further.<\/p>\n
The effort is part sport, part conservation strategy, as officials look for faster ways to protect native fish species and waterways.<\/p>\n
Northern snakeheads, a fish native to China's Yangtze River basin, have become established in the Chesapeake Bay area after first appearing there in 2002, according to a recent report in The New York Times.<\/p>\n
This species can reach about 90 centimeters in length, weigh almost 9 kilograms, survive out of water for up to four days, and even move on land to reach new habitats.<\/p>\n
Snakeheads are aggressive predators that can displace native species and create problems for fisheries and local communities that depend on healthy waters for recreation and food.<\/p>\n
To curb the snakehead infestation, Maryland is promoting bowfishing as a key management tool. During nighttime expeditions in shallow tributaries of the Potomac River, guides like Bill Bates teach anglers how to catch snakeheads using powerful compound bows\u2014a method that, according to The Times, can be more effective than traditional pole fishing in eliminating large numbers of these invasive fish.<\/p>\n
A recent peer-reviewed study by Maryland fisheries biologist Joseph Love found that bowfishing can increase overall snakehead mortality to approximately 25%\u2014enough to begin reversing population growth in the Chesapeake Bay and Potomac River.<\/p>\n
Experts also say climate change is exacerbating the problem. Warmer water, shorter winters, and heavier rainfall are further fueling the snakeheads' spread, as the fish migrate to new habitats through rain-swollen streams.<\/p>\n
The fish also reproduce over a long season, and females can lay up to 50,000 eggs twice a year, the Times newspaper noted.<\/p>\n
Damage to fisheries could negatively impact jobs, restaurant supply chains, and outdoor recreation traditions.<\/p>\n
Since completely eradicating snakeheads from the Mid-Atlantic region is no longer feasible, authorities have focused on population control. Federal agencies used electrofishing to capture snakeheads in the Chesapeake Bay basin, removing approximately 1,200 individuals between 2023 and 2025.<\/p>\n
However, this year the program was scaled back due to staff reductions.<\/p>\n
Maryland has also launched a bounty program to attract more anglers. Some snakeheads are tagged with blue tags issued by wildlife officials worth $200, and yellow tags worth $10; anglers receive the payment after reporting a fish kill.<\/p>\n
The state allocated $17,000 in federal funds under the program.<\/p>\n
Efforts are also underway to stimulate consumer demand. In 2024, Maryland lawmakers officially designated the fish "Chesapeake Bay Catfish" to make it more appealing on menus.<\/p>\n
Some restaurants now serve it as a local seafood dish, and advocates of the fish argue that creating a market for it could help reduce pressure on native species while supporting local businesses.<\/p>\n
